Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a new air supply tact, a new color (an air bypass passage, a used air exhaust duct, and a used air bypass passage). an exhaust duct connected to the air-to-air heat exchanger, the supply air tact having a first common flow path portion with the used air bypass path, and the exhaust duct having a second common flow path portion with the fresh air bypass path; a first common flow path between the supply air duct and the used air bypass path; a second common flow path between the air intake duct and the fresh air bypass path; An evaporator is installed in the riIs portion, and the condenser and evaporator are part of the heat pump, and the air supply tact has a floor connected to the used air bypass path, which is divided into 11 common flow paths. provide, 4
The Jl air duct is connected to the fresh air bypass passage and a duct floor is provided in the second common flow path, and the supply air duct and exhaust duct are provided with adjustable valves on both sides of the air-to-air heat exchanger. This valve allows you to switch the air conditioning state to the 1st, 2nd, and 3rd modes of the heat pump (heat pump and fresh air supply function, and the new ff!'f air supply function). This concerns the installation of air conditioning.

Such a device is described in German Painting Patent Application Publication No. 5ff430.
No. 47890. In this case, a fresh air supply duct is provided, which passes through the air-to-air heat exchanger and extends from the outside into the room. A first blower generates the flow in the fresh air supply tact. A used air exhaust tact extends from the room to the outdoors via a heat exchanger, and a second blower provided in this exhaust duct exhausts the used air from the room. In the exhaust tact, an evaporator is installed in front of the outlet, and in the supply air tact, a condenser is installed in front of the room. The evaporator and condenser form part of the heat pump. Furthermore, by using five regulating valves F, a bypass path (bypass tact) is obtained on both sides of the air-to-air heat exchanger between the supply and exhaust tacts.

In this way the air conditioner can be operated in different operating modes. In the mote, the new color Y
Heat exchange occurs in an air-to-air heat exchanger when introducing used air and withdrawing used air. When the bypass path is open and the heat exchanger is not activated, a pure heat pump operating mode is obtained, in which fresh air passes only through the evaporator and used air from the room only passes through the condenser. . In this heat pump operating mode, heat is absorbed from the fresh air and the absorbed heat is radiated into the room via the condenser. When the bypass is open and both the supply air duct and the tel air duct are open, the mix operating moat is turned on and ventilation and heating occur simultaneously.

This known system (1) requires control by a relatively large number of blocks, resulting in a multiple 4L11 configuration, which has the drawback of high manufacturing cost.

Therefore, an object of the present invention is to provide an air conditioner that can reduce the number of air conditioners and simplify the control for obtaining various air flows.

In order to achieve this purpose, the air conditioner of the great invention has a first three-way valve placed on the front side of the heat exchanger when viewed from the direction of the fresh air supply force, and a second three-way valve placed on the rear side of the heat exchanger. It is characterized by being placed on the side.

In a preferred embodiment of the present invention, the air-to-air heat exchanger is a heat pipe device, the evaporating section of the heat pipe device constitutes a part of the exhaust duct, and the condensing section constitutes a part of the supply air duct. The evaporating section and the condensing section are separated by a partition wall, and a large number of heat pipes are passed through the partition wall. This heat pipe heat exchanger allows for a compact structure with no moving parts.

Furthermore, in a preferred embodiment of the present invention, the heat pipe is arranged at an angle with respect to the direction of gravity.

The heat pipe contains an evaporable liquid that is evaporated by the flow of warm exhaust air and condensed by the flow of cool fresh air. When arranging several individual rows of pipes, an optimal countercurrent heat exchanger is obtained with heat conduction within a relatively narrow space and thus with a considerably high heat recovery effect.

The invention will now be described in detail with reference to the drawings.

The air conditioner has an air-to-air heat exchanger 3 placed in the center of a vertical housing 1 . This heat exchanger 3 is provided with a large number of heat pipes 3a, each of which is arranged as a package in an inclined manner, and is filled with a vaporizable working fluid. High temperature side of heat pipe 3a) γii+? Place SIs on the bottom
UL, the low temperature side 17iffj section is placed on the second side.

This arrangement allows fresh air to rise in the direction of the arrow 5 and air used in the room to descend in the direction of the arrow 7 via the heat exchanger 3. The fresh air flow duct and the used air flow duct are separated by a partition (separation wall) 9. A manhole flange 11 for an air supply pipe is provided outside the housing 1. Fresh air is artificial flange 11
The air flows in the direction of arrow 13 within the air conditioner, then flows towards the blower 15 in the direction of arrow 5, passes through the condenser 17, and then flows from the air conditioner in the direction of arrow 19 into the living space, i.e., indoor room 21. This flow path is called a fresh air supply tact.

The air used in the room flows into the housing 1 from the population 27.29 in the direction of the two arrows 23.25. Population 27
The used air flows in the direction shown by the arrow 23. This used air passes downward through the heat exchanger 3 in the direction of arrow 7, passes through the evaporator 33 in the direction of arrow 31,
Outside (outside air) in the direction of arrow 37 via outlet flange 35
leaks to. The series of channels through which the spent air flows in the direction of arrows 23.7.31 and 37 is called the exhaust tact. The blower 15 in the air supply duct (air supply duct) serves to forcibly send fresh air into the living space, that is, the indoor room 21, and the blower 39 serves to discharge used air to the outside.

The heat pump used has a compressor 41 and a condenser fit.
! It has an i-container 17 and an evaporator 33.

A three-way valve 43 in the air supply tact and a three-way valve 45 in the exhaust duct control the flow of air in the air conditioner. As shown in FIG. 1, when the three-way valve 4:3 engages the heat exchanger 3, this three-way valve 43 closes the supply air duct. When the three-way valve 45 engages the heat exchanger 3, this lift valve 45 closes the exhaust duct. The position of the three-way valve 43,45 shown in FIG. 1 is one end position. A bypass passage 47 between the supply air duct and the exhaust duct. 49 will be provided. These bypass paths 47. 49 is a valve 43. 45 can be closed.

The position when the three-way valve 43,45 closes the bypass path is the other end position of the three-way valve.

When the three-way valve 43 is in the position shown in Figure 1, the bypass passage 49 is open and used air flows in the direction of arrow 25 through the opening 51 of the bypass passage (see Figure 2). Then, the air passes through the blower 15, passes through the condenser 17 in the direction of the arrow 19, radiates heat in the condenser, and then flows into the room again.

Next, different operating states will be explained with reference to FIGS. 2 to 4. FIG. 2 corresponds to the state of the 11th air conditioner. In this operating state, only the action of the heat pump is performed by the three-way valve. Te side valve 43. =15 closes the passage through the heat exchanger 3. This means that the blower 39 introduces fresh air in the direction of arrow 13, but it flows directly into the evaporator 33 through the bypass passage 47 in the direction of arrow 53 and out of the outlet flange 35 to the outside. Therefore, only heat is absorbed from this introduced new color T air.

Since the three-way valve 43 also closes the heat exchanger 3, the opening 51
The used air introduced from the air passes through the blower 15 and the condenser 17 and returns to the room in the direction of the arrow 55. Therefore, in this case, it is in a pure heat pump mode (heating operation state), absorbs heat from outside, and this absorbed heat is used to heat the room 21 by the heat pump.

In the state of FIG. 3, the three-way valve 43,45 assumes an intermediate position. In these intermediate positions, the bypass passages 47, 49 are partially open and the heat exchanger is also partially open. This means that in addition to the flow in the direction of arrows 53 and 55 due to the heating operation state in Figure 2, the flow in the ventilation mode 5
yields 7.59. In this case, the air supply tact and the exhaust tact are fully opened together with the bypass path. The condenser forms a first common flow section of the supply air duct and the used air bypass, and the evaporator forms a second common flow section of the exhaust duct and the fresh air bypass.

FIG. 4 shows that the three-way valve 43.45 is connected to the bypass path 47. 49
Indicates the fully closed position. In this case, the air supplied by the blower 15.39 flows only in the direction of the arrow 57.59 from outside into the room and from inside to outside. In the heat exchanger 3, heat is absorbed from the indoor air led out in the direction of the arrow 59. This heat is imparted to the new air flow 57 and supplied to the room 21.

Thus, only two valves are needed for these three operating states, and these are the same as the previous: i! 'Adjust by I control device. Control of these valves: very f! It can be done in a simple way.
